Summary

The Austin City Council is set to authorize a contract with Santa Clara Construction, Ltd. for the Barton Creek Oak Acres Flood Risk Reduction Project. The total contract amount, including a contingency, will not exceed $3,874,247. This project aims to mitigate local flooding and improve roadway access to the Oak Acres neighborhood by replacing a low water crossing with a new bridge, increasing its elevation by approximately three feet. This enhancement will ensure the road remains passable during rainfall events of up to 12 inches in a 24-hour period. The project also includes approximately 3,800 linear feet of storm drainage improvements, removal of invasive species, and utility upgrades. Construction is expected to take 450 calendar days.

Citizen Impact

Residents in the Oak Acres subdivision (zip code 78735) will experience improved flood protection and continuous emergency access during heavy rainfall, though traffic will be reduced to a single lane for approximately six months during bridge construction.
